Find the sizes, and correct degrees on the DT bits, make a cheat sheet so you can then check sites at the bigger places selling bits. I know in the past they often had "sets" for PC 4212's, but in the last several years I don't see that language anymore, but all of the bits that were in the sets are still available as singles. I think they cut back on specialty packaging, but still have the inventory, just sold per piece now. I see Brian is still having bits marked as for Keller, and Akeda jigs, but they are just single bits. Maybe you are correct and B$D has ruined a good name.
